Meeting Abstract S8-1.5  Saturday, Jan. 5  Sperm Morphology and its Bearing on Decapod Phylogeny TUDGE, Chris; American University, Washington DC ctudge@american.edu The use of spermatozoal characters in helping to elucidate animal phylogeny (spermiocladistics – Jamieson, 1991) has recently been successfully applied in the decapod crustaceans. Most of the decapod taxa investigated for sperm morphology are published in […]

Meeting Abstract S8-1.3  Saturday, Jan. 5  Recent Mitochondrial Approaches to Decapod Phylogeny SCHUBART, Christoph D.; Universit�t Regensburg, Germany christoph.schubart@biologie.uni-regensburg.de During the past 15 years, mitochondrial DNA (mtDNA) has become the most widely used molecular marker for phylogenetic reconstructions of decapod Crustacea, with the large ribosomal RNA (16S rRNA) and cytochrome oxidase subunit I (CO1) as the most […]

Meeting Abstract S8-1.6  Saturday, Jan. 5  Evolution and Radiation of Shrimp-like Decapods: an Overview FRANSEN, C.H.J.M.*; DE GRAVE, S.; Nationaal Natuurhistorisch Museum – Natularis, Leiden, The Netherlands; Oxford University Museum of Natural History, Oxford, United Kingdom fransen@naturalis.nnm.nl Shrimp-like decapods (Dendrobranchiata, Stenopodidea and Caridea) are the basal lineages within decapod phylogeny. Recent morphological and molecular studies support the […]

Meeting Abstract S8-1.4  Saturday, Jan. 5  Development, Genes and Decapod Evolution SCHOLTZ, Gerhard; Humboldt-Universitaet zu Berlin gerhard.scholtz@rz.hu-berlin.de The analysis of complex spatiotemporal developmental patterns delivers a number of characters that can be useful for inferences on phylogeny and evolution. In addition the morphological nature of adult structures can be revealed based on ontogenetic studies. This is also […]

Meeting Abstract S8-1.7  Saturday, Jan. 5  Callianassidae and related families: steps towards a practical classification POORE, Gary C. B.; Museum Victoria gpoore@museum.vic.gov.au The Callianassidae sensu lato comprise 15 family or subfamily available names, 42 genus-level names and 256 described species, most erected in the last decade. The numbers of names used has gone up and down over […]

Meeting Abstract S8-1.2  Saturday, Jan. 5  An Overview of Decapod Molecular Phylogeny TOON, Alicia*; SEAMONS, Ryan ; ROBLES, Rafael; FELDER, Darryl L ; CRANDALL, Keith A ; BYU; BYU; Univ. of Louisiana; Univ. of Louisiana; BYU a_toon@byu.edu Decapoda is the most species rich group of Crustaceans containing numerous economically important and morphologically diverse leading to the large […]

Meeting Abstract S7-2.2  Saturday, Jan. 5  Living where the flow is right: How flow affects feeding in bryozoans. PRATT, M. C.; Mt. Holyoke College marneypratt@gmail.edu Bryozoans are suspension feeding colonial animals that remain attached to the substratum or other surfaces. Therefore, bryozoans rely on water flow to supply nutrients, eliminate wastes, and disperse gametes and larvae. The […]

Meeting Abstract S7-2.4  Saturday, Jan. 5  How kelp produce blade shapes suited to different flow regimes: A new wrinkle KOEHL, M. A. R. *; SILK, W. K.; Univ. of California, Berkeley; Univ. of California, Davis cnidaria@socrates.berkeley.edu Many species of macroalgae have flat, strap-like blades in habitats exposed to rapid water currents, but have ruffled �undulate� blades at […]

Meeting Abstract S7-2.1  Saturday, Jan. 5  Ecomechanics of marine mussels: do they really go with the flow? CARRINGTON, E; University of Washington ecarring@u.washington.edu Common features of many temperate rocky coasts are dense aggregations of bivalve mollusks, or mussel beds, which exclude other space occupiers and provide refuge habitat for a diverse assemblage of organisms. One key to […]

Meeting Abstract S7-2.3  Saturday, Jan. 5  Does Form Follow Flow? Crayfish Aesthetasc Morphology, Arrangement, And Flow Environment. MEAD, K. S.; Denison Univ., Granville OH meadk@denison.edu Crayfish sample their olfactory environment by flicking their antennules in a rapid down stroke followed by a slower return stroke. This motion thins the boundary layer surrounding chemosensory structures, facilitating encounter with […]
